JOINT FOR PIPES AND THE LIKE.

limitation :nea April a4, i922, serial No.

rlhis invention relates to jointsor pipes and the like formed:

1st-By malleable metallic rings uni'tedv by a heel or-'baseportion madein one piece which are placed in the space between -the two pipes or incoupling collars or coupling rings. p 2nd-By cement rings reinforcedwith rings of steel or other metal, plain or perforated, with or withoutsteel wire reinforcement and without ties, surrounding the rings ofmalleable metal.

The central strip or intermediate strips i of the rings of malleablemetal subsequently upset by caulking, hammering or compres sion so as toforce the outer' oit wing p0rtions of the yrings against the walls ofthe y pipes andthe rings thereby ensuring perfect fluid tightness of thejoints.

In order that the invention may be clearly understood, reference is madeto the accompanying drawings whereon- Figure 1 shows in section a sleeveor socket joint in accordance with the present invention.

. A\ strip of malleable metal comprising a centralportion l, two wings`2and 3 and a base 4 or heel portion, said strip being forced in a leadpress or cast in a suitable mould or rolled, the central portion 1 beingshorter, equal to or longer than the Iwings or portions 2, 3respectively. The outer and inner portions 2, 3 are subsequentlydattened or set back onto 'the central portion 1 so as to form a. strip5 of metal which is bent into a ring and driven in between the two pipes6, 7 yto be pointed. A iange 8 provided on the inner pipe 7 acts as astop for the heel or base portion of the ring 5. The central portion 1is upset by caulking. -During the cauliiing period the central portion 1opensthe wings or portions 2, 3 apart and compresses these against thewalls of the pipes so that they conform perfectly tothe form thereof.Y

Figure 2 shows in section another torni of' socket or sleeve joint. Theouter wing 9 of lthe ring of malleable metal is made with a triangularenlargement 10 which is 'formed in the ress during forcing of the stripas above escribed. The wings 2 and 12 are f attened' or vforced onto thecentral portion 11. The jointing strip is subsequently bent into a ringand placed in position in a recess in the pipe 14 which is provided witha shoulder l5 intended to act as a stop for the 556,282, and in, FranceJanuary` 20, 1922.

heel or base part 13 ofthe joint. The pipe 14 is also provided with arecessed part 16 of the same form as the triangular enlarged portion 10of the outer portion 9 of the ring. A beaded portion 17 projectinginwardl of the pipe 14 may be formed on the end o the said pipe so" astoretain the joint during transport and positioning of the pipes. Thejoint mayy be soldered it so desired after clamping the jointing ring inthe' space between the two pipes. The'pipe '18 is introduced in situinto the aforesaid space and it is only necessary to caulk the centralpart 11 of the ring in order to torce-the outer and inner portions 9 and12 against the walls of the' pipes 14 and against the outer surface ofthe end of the pipe.18. Packing of the joint may be completed bycaulking malleable metallic wires therein.

Figures 3 and 4 show twofurther constructional forms of jointing ringsmade of malleable metal. i

. The stripv which forms the ring 19shown in Figure 3 is made by castingin one piece in a mould or `forced in a press simultaneously with thewing 'portions 20-20 and the two central portions 21 and .if so desiredwith a part 22 adapted for use in ultimately ^centering the joint. Thetwo central portions 21 may be shorter, equal to, or longer than thewing portions 20.

The constructional form oity ring shown inv Figure 4 comprises the part23, wing `portions 24 with enlargements 25, the two centrai portions 26,the two inner wing portions 27 and the two heel or base portions 28. Thetwo central portions 26 may be longer, equal to or shorter than the wingportions 24 and 27.

\ Figure 5 vshows the application ot the consti-notional form ofjointing ring shown in Figure 3. The wing portions 2O are tlattened orforced onto the central portions 21. The blank is then bent into aringof a diameter to permit'of its being mounted on the pipesv` 29 and30 and the joint may then be soldered, proper precautions being taken toavoid sticking by soldering of the wing and central portions. This ring'is mounted on the ends of the pipes to be assembled and a ringr orcollar 31 oii steel or other suitable metal is positioned above and onone end ot the joint ring, another ring 32 or a collar being mounted onthe other end of the joint ring. The two central portions 21 are thencaulked so as to compress .may be protected by dan or torce the wingportions 20 against the rings or collars 31 32 and the adjacent surfacesot the pipes 29, 30. The joint may be protected by a layer 33 of juteimpregnated with asphalt, cement or other suitable material. r.lhe pipesmay be supplied or delivered with the joint mounted and caullred on theend ot onel of the pipes so that the other pipe can be inserted into thejointing ring and the centrai portion 2l thereafter caullred in order tocomplete the tluid tight assembly of the pipes in situv Figure 6 shewsthe application ot the constructional form of ring shewn in Figure4 incombination with a corrugatedor ribbed ring 34 of steel or other metal.The wing portions 24 and 27 are forced onto the central portions 26, andthe blank is then bent to diameter slightly larger than that ot the endsof the pipes to be assembled or jointed. The jointing ringis thensoldered, care being talren to avoid adherence by soldering of the wingportions 24-27 to the central portions 26. A, layer 35 or coating otasphalt is then. applied to the exterior of the ring in order to isolatethe metal from the cement mortar 36. 'lhe interior of the ring may alsobe coated with a layer of asphalt or .a sheet et asphalt may be causedto adhere thereto so as to protect the ring against the action ofinjurious waters., A. layer 36 of cement is provided between the ring 34and the jointing ring. rlhen atter setting et the cement mortar the ringis mounted or positioned on the` end of the pipe 37, which may be formedot asphalt or reinforced cement as described in the specitication of myapplication for Letters Fatent; or the aforesaid ring may be mounted orpositioned on the end of any other pipe having a cylindrical end. Thecentral portion 26 is upset by hammering, caulking or compression whichforces the wing portions 24, 27 against the walls of the pipe and thering. lt so desired the metallic ring 34 a layer 38 or covering of juteor other suitable material impregnated with asphalt or cement mortar.The above operations can be eil'ected in advance or in situ asfdesired.In order-to effect the last operations in situ the pipe 39 is positionedto the required length in the joint ring as shown in Figure 6; thecentral portion 26 is then swelled either by hammering, caulking orcompression so as to force the wing portions 24, 27 against the walls ofthe pipe 39 and the ring.

Figure 7 shews a jointing ring having the form oit' that shewn in Figure4 as applied for jointing purposes in combination with a ring 40 ofplain or perforated sheet steel bent and soldered at its joint. Thisring may be reinforced in case of necessity by/ a helical windin ofsteel Wire 41, the ends of which are sol ered onto the ring 40.- TheLocator wing portions 24 and 27 (Figure 4) of' the blank are flattenedor forced onto the central portions 26. 'Ehe blank is bent to form aring ot a diameter slightly greater than that of the ends of the pipesto be jointed and the joint ot the ring is soldered as hereinbeforeexplained. A sheet 42 or layer ot asphalt or other desired material isapplied to the exterior of the joint ring and in case of necessity alsoto the interior thereot'. The ring 46 of malleable metal and thehelically wound layer ot wire 4l are embedded in a layer oit cementmortar 43. lifter setting ot the mortar 43 the joint ring is mounted orpositioned on the ends of the pipes 44, either beforehand or in thefactory or in situ and the joint is then conipleted as' hereinbe-toredescribed with reterence to Figure 6. ln this constructionallapplication oit the ring-there may be any number of rings 40 andhelically wound layers of wire 4i et any desired pitch all according tothe pressures which the joint is to withstand.

Figure 8 shews a jointing ring formed in situ on the pipes already laid,the jointing ring being ot the kind shewn in Figure 4. ln thisarrangement a plurality et plain or perforated sheet steel rings 46 areshewn, these rings being bent and soldered at their joints and eachbeing reinforced by one or more than one steel wire winding. Afterattening or compression of the wing portions 24, 27 of the blank ofFigure 4 onto the central portions 26, the blank is bent directly on thepipes to a diameter corresponding to that of the ends ot the pi es andthe junction is then soldered, care being taken to avoid adherence bysoldering Y of the wing portions to the central portions. The ring isthen placed in position, then its exterior is covered with a layer ofasphalt or a sheet 47 of asphalt. is applied adhesively to the exteriorthereof. The plain or perforated sheets 46 with the Wire windings arethen laced in position centering ot these parts eing ensured by V-shapedties 48 or ligatures which may be loose or soldered to the rings 46. .Acollar 49 is placed at each end of the joint and the whole is surroundedby an iron sheet 50 perforated with one or more than one hole 5l. Cementmortar 52 is run in through the hole 5l thus embedding the wire woundrings 46, the wire windings and the malleable metallic jointing ring.After the cement mort-an has suiliciently set the elements 49, 50 of themould are removed and Whenithe mortar is quite hard or sui'icientlyhard, the central portions 26 are up-` set by caulking, hammering orcompressing in order to force the wing portions 24, 27 tightly againstthe Walls of the pipes 53, 54 and against the jointing ring. The heel orbase portions 28, Figure 4, butt or press against the cement mortar 52.

portions ma)7 be In'all the aforesaid jointsand aftervcaulk-v ing, thereremains suiicient space 55 between the,l central part of the jointingring of malleable `metal and' the ends of the pipes so that t-he lattermay bend slightly or accommodate themselves tothe ring without danger ofrupture ofthe pipes or of the ring. Instead of one central portion,4 twoor other suitable number of' these may vbe used.

The 4thickness of the central and win ual or unequal. The interiorpzgking olf the joints may be completed -by caulkingimalleable metallicwires therein, if necessary.`

The invention is not limited to the various arrangements shewn in thedrawings but may be applied to all kinds of oints in which thecompression is efected by a malleable ring provided with a recess orrecessesl in which a ring or rings are provided during making of thestrip, which are subsequently caulked, hammered or compressed to effectexpansion or swelling of the-joint, Such a joint has numerousadvantages. The interior or inner portions are so situated as to be veryeconomically manufactured; the wing portions of the ring adaptthemselves strictly to the Walls of the pipes and to those i of thecollars or rings; the joint once 'expanded by the interior caulking,hammering or compression is perfectly iuidtight and it the base. portionconstituting an abutment for engagement with a pipe member to'facilitate caulking'of the central 4extension whereby the'outerextensions are caused to separate and produce a fluid tight joint.

2. An article of manufacture as claimed in claim 1 characterized in thatthe com` bined thickness of the several extensions substantiallycorresponds to the thickness of the base portion.

8. As a newarticle of manufacture, a pair of` oppositelyarranged ringvlike members constructed according to claim 1 characterized by theprovision of a reduced web-like member' connecting the bases of the ringlike members j In testimony whereof IV have signed my name to thisspecification.
